Question 1:

Please show your answers to at least 4 decimal places. Find the directional derivative of the function f(x, y) = In (a + y ) at the point (3, 2) in the direction of the vector (2, - 2).Determine the gradient vector of a given real-valued function. Calculate the gradient of f(x, y) = xy at (x, y) = ( - 3, 3). Vf( - 3, 3) =Please show your answer to at least 4 decimal places. Determine the gradient of at, 3;) = 82'\" sin(5y) at (m, y) = ( 1, 1). we
